good job dear olegzen..
the first thing that looks not good in this render is colors harmony..may be changing camera position and using another view and control lights intensity for reducing hot spots (to bright areas) give viewer eye much more relaxing feeling..
and finally its really great job have fun buddy.

Hi Oleg,
these are quite complex scenes and I already see the process if time of posts is relative to time when renders were made.
I think that Kiarash is right, You should work on angles (think of what You want to show, composition is important) and maybe try to render darken scene next time. After that make final look in post processing. It is hard to achieve final crisp look with raw renders.
thanks for the comments :)
I will work more
